Susan Byrne, a member of the "Squawk Box" inaugural Portfolio Challenge, likes three companies that each raised their dividends three times each over the last decade.

"We continue to favor companies with strong positive cash flow that can support dividend increases each year even in slow and uneven economic times," the founder and chairman of Westwood Holdings said. The firm has held each of the stocks for more than six months.
